The soft light can be adjusted between the maximum power (shown on the display as
"00", i.e. 100%) and minimum power (shown on the display as "01", i.e. 1%). The
boiler is factory set to a value which is suitable for ignition with any type of gas
(approx. 33%).
The value set (expressed as a percentage) can be displayed as illustrated in
paragraph  3.6.2.
To  access the potentiometer “E” (Fig. 3.14), open the control panel as illustrated in
paragraph  3.1 and open up the service flap (Fig. 3.13).

The ignition delay can be adjusted to between 0 and 15 minutes. The delay is factory
set to 2 minutes.
The value set can be displayed as illustrated in paragraph  3.6.2.
To  access the potentiometer “C” (Fig. 3.14), open the control panel as illustrated in
paragraph  3.2 and open up the service flap (Fig. 3.13).
